Cobratoolbox crashes during initialisation on windows 10 (Matlab 2022b)

[trjhensen]

Please include a short description of problem here

Hi all, when I try to initialise the cobratoolbox on my desktop with "initCobraToolbox", my Matlab instance crashes. The following error was found "Access violation detected at 2024-03-04 09:38:49 +0000". I attached a MATLAB Log File to this issue that should provide a detailed overview on my current system and the error. Note that I have IBM cplex 12.10 installed and connected to my Matlab installation. I confirmed that I am on the latest version of the master branch. Let me know if there is anything wrong with my installation or if you need more information to solve the problem.

Thank you for your help.

Best regards, Tim

I hereby confirm that I have:

• [X] Tried to solve the issue on my own
• [X] Retried to run my code with the latest version of The COBRA Toolbox
• [X] Checked that a similar issue has not already been opened

Hellow friend,i had a same problem ,i think it's GCC/G++ not find,because final message in crash_dump.txt is :detected while a MEX-file was running. Matlab need GCC/G++ to compile and execute .mexw64,which in cobratoolbox\binary\win64\bin .Maybe we can install Mingw64 or TDM-GCC and add it to path,then use:mex -setup -v to find them.Don't forget use a path without "Space"(such as C:\TDM-GCC-64),otherwise, MATLAB does not recognize the path(such as C:\Program Files (x86)\Mingw64,because Program Files (x86) has a "Space")

Please how do I activate CPLEX as my solver on MATLAB? I am so lost trying to do this

Please how do I activate CPLEX as my solver on MATLAB? I am so lost trying to do this Hi,firend.Please install CPLEX 12.10 and include the matlab folder in into the matlab path（C:\Program Files\IBM\ILOG\CPLEX_Studio1210\cplex）, the directory I provided is the default installation location, the new version does not support matlab，Don't forget to get an academic license

IBM have decided not to release a MATLAB interface to the new version 20.1 of CPLEX. The previous version of CPLEX (12.10) can still be downloaded and used, apparently for the next 5 years. https://www.ibm.com/support/pages/downloading-ibm-ilog-cplex-optimization-studio-v12100

Please would everyone that uses CPLEX via MATLAB go to this page https://ibm-data-and-ai.ideas.aha.io/ideas/CPLEX-I-112 and request that IBM bring back the MATLAB interface?
